Fisher-Price responded to the recall Friday.

"While we continue to stand by the safety of all of our products, given the reported incidents in which the product was used contrary to safety warnings and instructions, we’ve decided in partnership with the Consumer Product Safety Commission (CPSC), that this voluntary recall is the best course of action, it said in a statement from General Manager Chuck Scothon.
